' OIL-BU NER.

To all whom it may concern:

Be it known th'atwe, P RMLYH. RYDER and CHARLES W. MOORE, citizens of the United States, residing at Bucyrus, in the county of Crawford and State of Ohio, have invented certain new and useful Improvements in anOil-Burner, of which" the following is a specification. a I

This invention relates to oil burners and more particularly to a burner adapted for using light oils such as kerosene, coal oil, or etroleum as fuel. I i

ne of the primary objects of the inven tion is to provide a low pressure oil burner adapted to use as a fuel, an oil whose density is not increased to an extent that will prevent its flow through the feed nozzle at. at temperature of 15 below zero Fahrenheit.

The invention further aims to provide an oil burner of this character which is'simple in construction,inexpensive to manufacture, and which may be easily installed, and which is designed to be usedwith a gravity feed system.

A further object of the invention is to provide an oil burner which will so thoroughly atomize and mix the oil with the air that} the oil will practically become a gas and can be ignited like a gas without any preheating of the burner or the oil.

The invention further aims to provide an oil burner especially adapted for use in crucible and reverberatory metal melting furnaces, cupola furnaces, annealing oven, core ovens, rivet furnaces, and similar furnaces where a blast of air isemployed to produce the necessary degree of heat.

The invention further aims to provide an oil burner which will cause the oil to be thoroughly atomized so that the oil will be burned without causing any smoke or oil constructed in accordance with our invention.

Fig. 3 .is anelevation of the nozzle detached. l

Referring to illustrated the preferred form of our inthe drawings, in which isvention, in which like numerals of reference 1 indicate like or corresponding parts through out the several views, the body A. of the burner comprises the hollow air chamber 1, j

the upper end of which is tapered so that the air is directed toward the upper end wall,

the latter being provided with a tapered passage 2 through which the air is ejected. The elbow 3, projecting from one side of the body and communicating with the air cham- 'the screw threaded shank 6 of the nozzle 7.

zle may be adjusted with respect to its position in the passage 2 so that it may be thrust outwardly through the opening or withdrawn as desired so that the flame may be properly regulated as the air pressure changes or the volume of oil is increased or decreased. It should be understood, however, that under normal conditions the end of the nozzle 8 is flush with the end of the passage 2 as shown. A look nut 9 is mounted on the shank 6 and is adapted to engage the end of the neck 4 tolock thenozzle in adjusted position. v

The square or hexagonal end of the nozzle provides a head whereby a wrench may be applied to adjust the nozzle and projecting from this head is the nipple ll to which is attached one end of a'union 12which comprises the complementary members 13 and 14 held together by the ring member 15 in a manner similar to the standard union. In

terposed between the complementary members 13 and 14, however, is a screen panel 16 and this member 14 is connected to the valve 17 to which is joined the oil supply pipe 18 which of course, may lead toealtanko, or other source ofroilsup ply, Inasmuchmas.

the burner is especially adapted for gravity feed systems, the oiltank should'be disposed at a level higher than the burner'so that the oil will feed by. gravity through'the nozzle and its volumeniaybe governed by opening or closing the va'lve.-17-.v The oil p'assesi through the screen panel 16 and'into the passage-Way 8 and therefore any" foreign substanceis arrested by the screenso that clogging of'th'e nozzle is prevented: Vhen the oil reaches the end of the nozzle the blast of air passing. through the passage 2 thforoughly atomizes theoilso that p'erfectvcom- 'bustionisassured.
